Hi @jeff and @nathanletwory,
Thanks for your engagement!
I will try to answer your questions and help with files etc.
All NURBS surfaces, no meshes involved.
I can confirm that in the file from which I took the screenshots above, all bleeding through glitches disappear when I unlock the layer with the objects that cause the bleeding.
I can confirm this behaviour in other files too.
I set up an additional simple test file. It shows the bleeding through glitch independent from locked/unlocked layers status.
Maybe the guy in the picture is a special case, as all other objects seem to behave correctly. The guy is a single trimmed surface, with texture, self-illuminating, dense outline w/ high control point count.
I will try to find other examples. Meanwhile we can figure out what makes this guy so special
